Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636518, here are decompositions:

5 + 8636513 = 8636518
131 + 8636387 = 8636518
257 + 8636261 = 8636518
281 + 8636237 = 8636518
389 + 8636129 = 8636518
431 + 8636087 = 8636518
461 + 8636057 = 8636518
479 + 8636039 = 8636518

Showing the first eight; more decompositions exist.
